释义

Definition of elutriate in English:

elutriate

verb ɪˈl(j)uːtrɪeɪtəˈlo͞otrēˌāt
[with object]Chemistry
  • Separate (lighter and heavier particles in a mixture) by suspension in an upward flow of liquid or gas.

    〔化〕淘析,淘选

    the unelutriated cells showed a broad distribution of cell volume compared with the elutriated fractions
    Example sentencesExamples
    • A scavenging, or sorting, model involves fluidization of poorly sorted Mawson Formation lapilli-tuffs, perhaps with a contribution from volcaniclastic rafts, with the fine particles elutriated then injected to form clastic dykes.
    • In the laboratory, the material from each core retained on the 250 - [micro] m mesh was elutriated in supersaturated sucrose solution to remove juvenile macrofauna and sediments were sorted to remove larger macrofauna.
    • We infer that the material for the largest dykes was elutriated from their host's matrix.
    • Alternatively, the coarser grain-sized intrusions seen at outcrop may be testimony to high flow velocities during fluidization and injection, with any finer-grained sand or silt having been elutriated from the system.

Derivatives

  • elutriation

  • noun ɪl(j)uːtrɪˈeɪʃ(ə)nəˌlutriˈeɪʃ(ə)n
    Chemistry
    • Approximately 2 x 10 exponentially growing HeLa-S3 cells were synchronized by size using centrifugal elutriation in a J6 MI centrifuge and at least 15 size-separated fractions were collected.
      Example sentencesExamples
      • In this volcanic setting elutriation was driven by magmatic heat, but the production of relatively finer-grained clastic dykes by elutriation of material from coarser ill-sorted sources may be significant in many settings.
      • To examine Tetrahymena RAD51 expression through the cell cycle, a synchronous population was obtained by centrifugal elutriation.
      • The cells in different cell cycle phases were collected, and cell cycle distribution in each of the fractions from centrifugal elutriation was confirmed by flow cytometry.
      • G1 daughter cells obtained by centrifugal elutriation were released into fresh medium and monitored every 30 min thereafter for the presence of Trf4p on chromosome spreads, for nuclear morphology, and for spindle morphology.

Origin

Mid 18th century: from Latin elutriat- 'washed out', from the verb elutriare, from e- (variant of ex-) 'out' + lutriare 'to wash'.
